` THE GRAPHIQVCWPHOTOfLITHS 3:41 PARK PLAOEJLY TA'rEs IMPROVEMENT IN AIR-PUMP FAUCETS.

Specification forming part of Letters Patent N0. 162,@8, dated May 4,1875; application tiled September 4, 1874.

To all whom t may concern Be it known that I, THOMAS BINGHAM, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Air-Pump Faucets; and I do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawings forming part of this specicttion, in which- Figure l is a top view of my improved airpump faucet, and Fig. 2 is a longitudinal section of the same.

Similar letters of reference in the accompanying drawings denote the lsame parts.

rEhe object of my invention is to draw liquids from a barrel, cask, or other similar receptacle Without removing the bung or perforating the cask to allow the ingress of air to the interior, and at the saine time to secure a more rapid flow of the liquid than when the ordinary faucet is used in connection with avent; and to these ends my invention consists in the employment of an air-chamber situated on the upper side of a faucet, and provided with a piston. piston-rod and handle, and valves governing the ingress and egress of air into passages connecting the air-chamber with the outer air and the interior ot' the barrel, by means of which air drawn from the outside ofthe barrel can be compressed and forced into the barrel, causing a rapid flow of the liquid contained therein through the faucet, all of which I will now proceed to describe.

In the accompanying drawings, A represents a faucet or spigot, provided with the ordinary plug B, having the passage C, and closed or opened by the revolution of the handle D, in the usual manner. E is an air-chamber, having screw-threads cut on its lower interior circular end, which are screwed over a screwthreaded circular projection, o, attached to the upper side ofthefaucet,thus securing thechamber E air-tight to the faucet. S is the cover of the chamber E, fitting itair-tight, and provided with an air tight stuffing-box, in which the piston-rod G, carrying the piston F, is made to resage N leading thence into the interior ofthe barrel or other receptacle from which the liquid is to be drawn. L is a valve opening upward at the junction of the air-passages K and N, the play of said valve being limited by an adjustable screw-plug, M.

The operation of my improved air-pump faucet is as follows: The passage C being opened, by turning the plug B bymeans ofthe handle D, the handle H is raised, elevating the piston F, rarefying the air in the chamber E, and causing the outer air to enter the air-chamber through the passage I and valve J, which is forced upward, the valve L being closed. On the descent of the piston the valve J is closed by the pressure of the air, and the latter, in a compressed state, is forced into the passage K, and, raising the valve L, is forced through the passage N into the interior ofthe barrel, thus forcing out the liquid rapidly through the passage C in the faucet into a vessel provided to receiveit.

I claim- The faucet A, provided with the liquid-passage G, plug B, air-passages I K N, and valves J L, in combination with the airchamber E, provided with the piston F and piston-rod G, substantially as described, and for the purpose set forth.

THOS. BINGHAM.
